c894696188 rtlwifi: rtl8821ae: replace _rtl8821ae_mrate_idx_to_arfr_id with generic version
Function _rtl8821ae_mrate_idx_to_arfr_id is functionally identical to
the generic version rtl_mrate_idx_to_arfr_id, so remove
_rtl8821ae_mrate_idx_to_arfr_id and use the generic one instead.

This also fixes a missing break statement found by CoverityScan in
_rtl8821ae_mrate_idx_to_arfr_id, namely: CID#1167237 ("Missing break
in switch")

Thanks to Joe Perches for spotting this when I submitted an earlier patch.

3d71c3f1f5 iwlwifi: mvm: check return value of rs_rate_from_ucode_rate()
The rs_rate_from_ucode_rate() function may return -EINVAL if the rate
is invalid, but none of the callsites check for the error, potentially
making us access arrays with index IWL_RATE_INVALID, which is larger
than the arrays, causing an out-of-bounds access.  This will trigger
KASAN warnings, such as the one reported in the bugzilla issue
mentioned below.

f0193d3ea7 change semantics of ldisc ->compat_ioctl()
First of all, make it return int.  Returning long when native method
had never allowed that is ridiculous and inconvenient.

More importantly, change the caller; if ldisc ->compat_ioctl() is NULL
or returns -ENOIOCTLCMD, tty_compat_ioctl() will try to feed cmd and
compat_ptr(arg) to ldisc's native ->ioctl().

That simplifies ->compat_ioctl() instances quite a bit - they only
need to deal with ioctls that are neither generic tty ones (those
would get shunted off to tty_ioctl()) nor simple compat pointer ones.

Note that something like TCFLSH won't reach ->compat_ioctl(),
even if ldisc ->ioctl() does handle it - it will be recognized
earlier and passed to tty_ioctl() (and ultimately - ldisc ->ioctl()).

For many ldiscs it means that NULL ->compat_ioctl() does the
right thing.  Those where it won't serve (see e.g. n_r3964.c) are
also easily dealt with - we need to handle the numeric-argument
ioctls (calling the native instance) and, if such would exist,
the ioctls that need layout conversion, etc.

All in-tree ldiscs dealt with.

There is no reason to open code what the switch setup function does, in
fact, because we just issued a switch reset, we would make all the
register get their default values, including for instance, having unused
port be enabled again and wasting power and leading to an inappropriate
switch core clock being selected.

bf3b452b7a net: dsa: bcm_sf2: Fix unbind ordering
The order in which we release resources is unfortunately leading to bus
errors while dismantling the port. This is because we set
priv->wol_ports_mask to 0 to tell bcm_sf2_sw_suspend() that it is now
permissible to clock gate the switch. Later on, when dsa_slave_destroy()
comes in from dsa_unregister_switch() and calls
dsa_switch_ops::port_disable, we perform the same dismantling again, and
this time we hit registers that are clock gated.

Make sure that dsa_unregister_switch() is the first thing that happens,
which takes care of releasing all user visible resources, then proceed
with clock gating hardware. We still need to set priv->wol_ports_mask to
0 to make sure that an enabled port properly gets disabled in case it
was previously used as part of Wake-on-LAN.

052858663d net: phy: sfp: remove sfp_mutex's definition
The sfp_mutex variable is defined but never used in this file. Not even
in the commit that introduced that variable.

Remove sfp_mutex, it has no purpose.

511cfd580f r8169: set RX_MULTI_EN bit in RxConfig for 8168F-family chips
It has been reported that since
commit 05212ba813 ("r8169: set RxConfig after tx/rx is enabled for RTL8169sb/8110sb devices")
at least RTL_GIGA_MAC_VER_38 NICs work erratically after a resume from
suspend.
The problem has been traced to a missing RX_MULTI_EN bit in the RxConfig
register.
We already set this bit for RTL_GIGA_MAC_VER_35 NICs of the same 8168F
chip family so let's do it also for its other siblings: RTL_GIGA_MAC_VER_36
and RTL_GIGA_MAC_VER_38.

Curiously, the NIC seems to work fine after a system boot without having
this bit set as long as the system isn't suspended and resumed.

8cc1da96d1 net: cdc_ncm: use tasklet_init() for tasklet_struct init
The tasklet initialisation would be better done by tasklet_init()
instead of assuming all the fields are in an ok state by default.

This does not fix any actual know bug.

2a1e89df78 net: socionext: clear rx irq correctly
commit 63ae7949e9 ("net: socionext: Use descriptor info instead of MMIO reads on Rx")
removed constant mmio reads from the driver and started using a descriptor
field to check if packet should be processed.
This lead the napi rx handler being constantly called while no packets
needed processing and ksoftirq getting 100% cpu usage. Issue one mmio read
to clear the irq correcty after processing packets

2645060834 net/mlx4_core: Fix warnings during boot on driverinit param set failures
During boot, mlx4_core sets the driverinit configuration parameters and
updates the devlink module on the initial values calling
devlink_param_driverinit_value_set().
If devlink_param_driverinit_value_set() returns an error mlx4_core
reports kernel module warning.

This caused false alarm during boot in case kernel was compiled with
CONFIG_NET_DEVLINK off.
Fix by removing warning reported in case
devlink_param_driverinit_value_set() fails.

This actually makes the function mlx4_devlink_set_init_value()
redundant to using directly devlink_param_driverinit_value_set() and so
removed.

It fixes the following kernel trace:

 mlx4_core 0000:00:06.0: devlink set parameter 0 value failed (err = -95)
 mlx4_core 0000:00:06.0: devlink set parameter 1 value failed (err = -95)
 mlx4_core 0000:00:06.0: devlink set parameter 4 value failed (err = -95)
 mlx4_core 0000:00:06.0: devlink set parameter 5 value failed (err = -95)
 mlx4_core 0000:00:06.0: devlink set parameter 3 value failed (err = -95)

e70a57fa59 cxgb4: fix thermal configuration dependencies
With CONFIG_THERMAL=m, we get a build error:

drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.c: In function 'cxgb4_thermal_get_trip_type':
drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.c:48:11: error: 'struct adapter' has no member named 'ch_thermal'

Once that is fixed by using IS_ENABLED() checks, we get a link error
against the thermal subsystem when cxgb4 is built-in:

drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.o: In function `cxgb4_thermal_init':
cxgb4_thermal.c:(.text+0x180): undefined reference to `thermal_zone_device_register'
drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.o: In function `cxgb4_thermal_remove':
cxgb4_thermal.c:(.text+0x1e0): undefined reference to `thermal_zone_device_unregister'

Finally, since CONFIG_THERMAL can be =m, the Makefile fails to pick up the
extra file into built-in.a, and we get another link failure against the
cxgb4_thermal_init/cxgb4_thermal_remove files, so the Makefile has to
be adapted as well to work for both CONFIG_THERMAL=y and =m.
